Rationale: This Aerospace Recommended Practice (ARP) has been superseded by the document AIR1900, “Guide to Temperature Monitoring in Aircraft Gas Turbine Engines”. AIR1900 consolidates the contents of this document (ARP464) plus ARP465 “Flange - Thermocouple” and ARP485 “Temperature Measuring Devices Nomenclature”. As such, AIR1900 provides a comprehensive document covering temperature monitoring in aircraft gas turbine engines making the contents of ARP464, ARP465, and ARP485 redundant and unnecessary. This document consolidation strategy was agreed to by the SAE E-32 Aerospace Propulsion Systems Health Management Committee as part of the Committee’s Master Plan.
